This article is a good start, but given that the cheapest purchase of the JDMK is $6k, wouldn't it be better to mention some open source alternatives that provide similar functionality? Considering that people who have forked out six grand for this already know more than a single page introduction will tell them, and that people who haven't yet purchased it will probably want to start playing around after reading the article, it would have been nice to see ways to get started immediately.
